If you are a snow traveller now is the best time to travel. Another best time is from March to September. Other than usual spots, let me share some unexplored places which might be helpful for your travel. Sangestar Tso lake is filled with nature
Chagzam bridge is 25km long with some fine metallurgy techniques. To feel cool waters you can try visiting Nuranang waterfalls. You should try taking a stroll round Madhuri lake. Don't miss out on biting gyapa khazi, zan and thukpas besides yum momos. Happy safe journey.
